GS Renovation designs and builds extensions across Wembley, tailored to the 1930s and interwar semis that dominate HA9. With over 30 years of building experience in Brent, we take on rear, side-return and wrap-around projects, using the generous plots these suburban houses enjoy to add genuine, well-built living space rather than a cramped box on the back.
Rear and side extensions on Wembley plots
The wide plots and side passages of Wembley's interwar semis lend themselves to side-return and wrap-around extensions that many tighter London terraces cannot manage. A typical HA9 project extends the kitchen into the side alley and out to the rear, creating an open-plan kitchen-diner that opens onto the back garden. We dig and pour the foundations to the depth building control requires, allowing for any nearby trees on these leafier suburban plots, then build up in matching brick or render.
Steel beams carry the old rear wall once the opening is formed, and we tie the new roof, whether a flat roof with lantern or a pitched addition, into the existing 1930s structure. Because these are semi-detached pairs, a party wall notice to the adjoining owner is usually part of the process. We manage the groundworks, the steel, the roof and the weathertight shell as a continuous sequence.
Planning and building control in Brent
Whether your Wembley extension is permitted development or needs a full planning application depends on the property and how far you go. Many single-storey rear extensions on these interwar plots fall under permitted development, but double-storey work, anything close to a boundary, or a home already extended will often need permission from Brent Council. We assess your specific house honestly and, where required, help prepare and submit the planning application rather than leaving you to guess.
Every extension, whatever its planning route, must meet building regulations. Brent building control inspects the foundations, the damp proofing, the steelwork, insulation and drainage at set stages. We book these inspections and keep the paperwork straight so your completion certificate arrives cleanly. From first sketch to the final fit-out of kitchen, bathroom, plastering and decoration, one team runs the whole job across HA9.
